orL FILTER.

Application filed November This invention relates to improvements in an oil filter, the general object of the invention being to provi le means for filtering the oil after it leaves the pump of an internal combustion motor and before reaching the bearings of the motor.

Another objectof the invention is to permit the unfiltered oil to have accessto the oil gauge so that the filter will not interfere with the proper working of the gauge de- Vice.

A further object of the invention is to provide means for priming the pump system if, for any reason, the pump should fail to work and for providing ready access to the parts for cleansing purposes.

This invention also consist-s in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sev eral views and in which Figure 1 is a sectional View through portion of a vehicle showing the invention in use.

Figure 2 is an enlarged sectional view of the device itself.

Figure 3 is a top plan View.

Figure 4 is a section on line t-- l of Figure 2.

Figure 5 is a section on line 55 of Figure 4.

Figure 6 is a detail View of the spring bracket.

In these views, 1 indicates a pair of brackets which are fastened to the dash 2 of the motor vehicle A, the motor of which is shown at B. The brackets are placed above the motor, as shown, and a cross piece 3 is bolted to the brackets, the bolts 4 passing through slots 5 in the cross piece so that the same is adjustably connected with the brackets. Threaded rods 6 extend through holes in the cross piece and are adjustably held in position by means of the wing nuts 7 which rest on the cross piece. The lower ends of the rods 6 are of hook-shape and are each adapted to engage any one of a plurality of holes 3 formed in each limb of a U-shaped member 9 which has a flan e supporting 8 192%. Serial No. $18,783.

plate 10 connected with its bight and which is adapted to support a jar 11 which is preferably formed of glass. Thus the jar is suspended from the cross piece by the threaded rods 6. A jar rap'12 is also fastened to the cross piece 3, by means of a cross-shaped bracket 13 formed of spring material and a bolt 14 which fastens the bracket 13 to the cross piece and which is in turn fastened to T-coupling 15 by the plate 16 which is held in place by the cock 17 provided with the funnel 18. The cap carries a gasket 19 and by tightcning the nuts 7 on the rods 6 the mouth of the can be forced tightly against the gasket so as to make a tight joint between the cap and jar. A pipe 20 projects into the jar from the coupler 15 and a tube 21 connects the coupling 15 with the oil gauge 22 on the instrument board of the W Vehicle. A pipe 23 is connected with a pipe 24- which extends through the cap into the jar and said pipe 23 is connected with the oil pump 2% of the motor B. A small casing 25, of semi-circular shape incross section, is fastened to the inner face of the cap and extends within the A ring 25. is soldered or otherwise fastened to the casing 25 and has a flange which is soldered or otherwise fastened to the cap. The bottom of this casing is open and a sheet 26 of chamois or other filtering cloth is stretched over the same by a spring strip 27. Wire mesh 28, or the like, is held in spaced relation to the sheet 26, at the bottom of the filter casing by being fastened to the small casing 29 which overlaps the lower part of the casing 25 and is frictionally held in place by engagement with this strip 27. A filtering medium 28, such as cotton or the like, is placed between the wire mesh 28 and the sheet 26. Thus the casing 25 and its associated parts form a filtering chamber into which oil from the jar can enter through the filtering mediums 26 and 28. A tube 30 connects the filtering chamber With the bearings to be lubricated and a pipe extends through the cap into said filtering chamber and has a cook 31 attached thereto which is provided with a funnel 32. The casing 29 is held in place by means of the spring latch 33.

From the foregoing it will be seen that the oil forced through the tube 23 by the pump 2% will enter the jar and will rise in the same until it reaches the filtering casing. Some of this oil will enter the pipe 20 and will thus act on the pressure gauge and as the pump continues to operate the oil will be forced through the filtering mediums 26 and 28 into the filter casing and it Will pass from this casing through the pipe 30 back to the bearings and the crank case Where it will again be picked up by the pump and returned to the filter. Thus the oil Will be thoroughly cleaned before it is delivered to thebearings. Thepump can be primed by pouring oil into the jar through means of the funnel 18, cock 1?, T-coupling 15 and pipe 20 and the. filtering medium can be cleaned by pouring a cleaning medium through the funnel 32 and cook 31 and tube 35. The jar can be easily and quickly removed and the Water and other foreign matter removed from the same by slackening thenuts 7 on the rods 6 so that the supporting member and the jar can be removed. As Will be seen, the pressure Within the jar is communicated to the pressure gauge so that I may place an oil cooler C in the system for cooling the oil before it reaches the filter.

It is thought from the foregoing description that the advantages and novel features of my invention Will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.

What I claim is V p A filter of the class described con'iprising ajar, a cap for cooling the same. a bracket,

a jar holder, hook members adjustably connected with the holder, means for adj ustably connecting the hook members With the bracket, a filter-chamber carried by the cap and extending into thejar, an outlet pipe passing through the cap into the chamber and means for introducing the material to be filtered into the container to one side of the chamber.

In testimony whereof I afiix my signature.

JOHN T. MCCUTCHEON.
